1. Install pnpm
2. pnpm i to install deps
3. Maybe have to install node with pnpm env use --global latest for latest version
4. Build with pnpm build
5. Serve dist directory with whatever webserver you want. It is static.

With docker the following compose file will work for Caddy. (Note the included docker-compose file uses port 4242 on the host).

services:
  meowjam:
    image: caddy:2-alpine
    ports:
      - "80:80"
    volumes:
      - ./dist:/usr/share/caddy:ro
      - ./caddy_data:/data
    restart: unless-stopped

A rust, web view based version of the app (as it was originally developed) can be found on the tauri branch.
